🔍 Key Concepts

• Evaporator/distiller flow paths – where salt water enters, where brine leaves, and where distillate/feed water connections usually are located • Relationship between the side view and rear view of the same unit – each lettered fitting appears in both views • Typical positions of inlets vs outlets – inlets usually lead into the main shell; outlets often are at the lowest point or on discharge lines

💭 Think About

• On the side view, trace the path of sea/salt water through the unit: where does it first enter the shell and where does the concentrated brine leave? Then match those fittings to the rear view label "M" • Look at the vertical and horizontal piping on the rear view: does item "M" appear to be connected to a pump suction, a discharge, or a return line? What type of connection would that most likely be? • Compare the relative heights of all the connections: which ones would logically be brine outlets (heavier, at the bottom) and which would be inlets or returns (higher on the shell)?

✅ Before You Answer

• Verify on the side view which letter corresponds to the point where sea/salt water first enters the unit and then find that same letter location on the rear view • Confirm whether item M is above or below the lowest point of the shell – a true brine outlet is usually at or very near the lowest point • Check if item M is tied into the heating/jacket water circuit or into the shell where seawater/feed water is introduced – this will help rule out jacket water inlet versus the other options
